My Wii Remote doesn’t work with my Wii MotionPlus attached…
Ensure your Wii MotionPlus is correctly inserted, and that the LOCK switch has been slid in the direction of the arrow.
You should also check for common Wii Remote problems – such as battery level, whether your Wii Remote has been synced, etc. – that may affect the performance of your Wii Remote.
If there is still no response, disconnect and reinsert the connector plug of your Wii MotionPlus several times, check that it is properly inserted and try again.
